2010 Map of Big Costilla Peak

About this map

Big Costilla Peak dominates the high-altitude landscape of this Taos County survey, serving as a primary landmark for this mountainous border region between New Mexico and Colorado. The hydrology of the area is defined by the significant catchments of Costilla Reservoir and the Costilla Reservoir Dam in the southeast, which collect runoff from a network of alpine sources including Santistevan Creek and Allen Creek. The high-country drainage system is further detailed through features like Glacier Lakes, Seven Lakes, and sequentially named bodies such as Lake Number One and Lake Number Two.
